Installation Guide

Mirantis Secure Registry (MSR) supports two installation scenarios designed to meet most customer needs:

• High availability installation

• Single host installation

The following comparison highlights key differences to help you choose the most appropriate option for your environment.

Installation Scenario	Detail
High Availability	Deployment of MSR in a high availability configuration on Kubernetes using Helm charts. Benefits Provides the highest resiliency and uptime. Leverages Kubernetes orchestration with three or more nodes running in an active-active configuration. Includes guidance for installing PostgreSQL and Redis in a high availability configuration. Use case Production environments of medium to large enterprises, where uptime is critical.
Single host using Docker Compose	High availability is not supported. Thus, if the MSR instance becomes unavailable, there is no orchestrator to provide redundancy. Benefits Does not require Kubernetes or Helm/OCI Charts. Use case Non-production environments, or smaller enterprises or office sites. Also suitable for non-Kubernetes environments.

Some organizations may have unique infrastructure requirements or prefer custom deployment strategies that extend beyond the scope outlined here. While Mirantis supports a wide range of use cases, official support is limited to the configurations described above.

Contact Mirantis Professional Services for assistance with specialized installations or custom deployments.
